Multi-Rate Multi-User Digital Wireless Communication Techniques
Phone: (310) 530-1410
Physical Optics Corporation (POC) proposes to design schemes that will extend multiuser detection and interference suppression technologies. This will be done in the context of multiuser Code Division Multiple Access (CDMA) communications for wireless multirate and variable-rate network communication applications. The importance of this project lies in its combination of advanced technologies with a comprehensive understanding of different service requirements. Integrating these attributes, POC can provide a useful network design strategy that offers multi-rate and variable rate flexibility, increased system capacity, improved communication quality, and, simultaneously will make efficient use of available channel resources. Specifically, POC proposes to develop an integrated multi-user, multi-rate CDMA receiver technology in conjunction with a software radio technique. The software radio concept centers on the use of a wideband A/D and D/A connector placed as close to the antenna as possible. This technique will not only be immediately applicable to the proposed multi-use, multi-rate CDMA communication system, but will also have the flexibility to be expandable to other communication functions.
